Introduction The 1998 Nobel Prize for Chemistry was awarded jointly to Professors Pople and Kohn for the development of computational methods in quantum chemistry and, in particular, for the development of density-functional theory (DFT). The award acknowledges the enormous strides that these men and their disciples have taken during the last three decades and celebrates the revolution in chemi...

Hybrid inorganic-organic materials comprising organic functional groups tethered from silica surfaces are versatile, heterogeneous catalysts. Recent advances have led to the preparation of silica materials containing multiple, different functional groups that can show cooperative catalysis; that is, these functional groups can act together to provide catalytic activity and selectivity superior ...

SHIRAI, M., NAKAMURA, M. and MATSUDA, S. Differential Diagnosis between Functional and Organic Impotence by Radioisotope Penogram Following Visual Sexual Stimulation. Tohoku J. exp. Med., 1973, 111 (2), 187-195 The radioisotope penogram, which measures changes of blood flow through the penis, was developed and applied as a measure of objective differentiation between functional and organic impo...

OBJECTIVE Comparing health-related quality of life (HRQOL) in children suffering from functional and organic gastrointestinal disorders and to identify predictors for HRQOL. METHODS Children with functional (n = 70) and organic (n = 100) gastrointestinal disorders, aged 8-18 years and referred to a pediatric gastroenterologist, completed questionnaires assessing pain severity, coping, and HRQ...

This chapter is written with the assumption that the reader has a basic knowledge of organic chemistry and is at least familiar with the terminology used to describe the parts of an organic molecule. The goals of this chapter are to define the term functional group, review the major chemical properties or characteristics inherent to any given functional group, relate these chemical properties o...

The genes involved in organic hydroperoxide protection in Agrobacterium tumefaciens were functionally evaluated. Gene inactivation studies and functional analyses have identified ohr, encoding a thiol peroxidase, as the gene primarily responsible for organic hydroperoxide protection in A. tumefaciens. An ohr mutant was sensitive to organic hydroperoxide killing and had a reduced capacity to met...
